After FLP/FRT-dependent mitotic recombination, homozygous mutant cells lack Gal80, allowing active Gal4 to activate marker genes and any gene under the regulation of UAS (Wu and Luo, 2007).
The non-canonical WNT5A skewed them into a pro-inflammatory category as measured by inhibitory cell surface marker LAG3, LY49E, NKG2A and activated marker CD69 and FASL.
Each of the individual cell types studied showed signs of significant inflammatory pathway activation within 5 min, although interestingly this did not include NF-κB, which was the most consistently activated marker 5 min after LPS.
In co-infected animals, a higher proportion of macrophages in the alveolar and interstitial spaces expressed both classical and alternatively activated markers and produced the regulatory cytokines TGFβ and IL-10, as well as higher arginase levels than in mice infected with P. aeruginosa alone.
Recently, a dual role of APC in the WNT-signalling pathway has been suggested with both activating and repressing mechanisms [ 44] which could explain the patterns found in patient 2 where APC has gained activating markers (Additional file 2, Figure S4B) In addition, patient 1 shows an activation of several known repressors of the WNT-pathway.
Expression of NKG2A-specific shRNA did not affect the expression of the activating markers NKp44 on NK cells and CD25 on T cells.
We stained sequential sections with antibody against FGF10 and stromal cell markers (CD68; macrophage marker, α-smooth muscle actin; activated fibroblast marker, CD3; T-cell marker).
Even when stimulated with low LPS concentrations (ranging from 0.01 EU/ml to 100 EU/ml), monocytes reacted by releasing vast amounts of cytokines and activating surface marker expression, which emphasizes the toxicity and potential danger of masked LPS.
Our data shed light on the complex coregulation of RUNX1 by ΔNp63 and p53, leading to a role for RUNX1 in the switch from proliferation to differentiation by repressing the cell cycle and activating a marker of early keratinocytes differentiation.
